@sounaipr. Thats exactly what I did mean (question was badly written because of a sorely lack of knowledge). Thanks for clearing it up.
You felt it coming, how can I find out (the easy way preferably) if a model consists of multiple textures (as in the case of Giants and Werewolves). Does their exists a list on the Net which shows this kind of information, if so an url would be nice. Could be quite/very valuable for AV package creators. Or do I dare to suggest it, could you supply us with such a list (at least for the creatures which have been Av-tized by now). I'm very curious what creatures can have Variant Groups.
CSA is a type I'm afraid. I ment to write SCA (Skyrim creatures alive) ;-(
If you (or anyone else) are into wildlife mods might I suggest in addition to RWS and SRAP and Pride to give the following mods a try: http://skyrim.nexusmods.com/downloads/file.php?id=4955, http://skyrim.nexusmods.com/downloads/file.php?id=14320, http://skyrim.nexusmods.com/downloads/file.php?id=11555 and of course http://skyrim.nexusmods.com/downloads/file.php?id=8565. This in combination with http://skyrim.nexusmods.com/downloads/file.php?id=10886 and http://skyrim.nexusmods.com/downloads/file.php?id=8601 makes for a REALLY great and immersive experience.
Its so easy to miss mods even when on the SkyrimNexus. If anyone else knows about (good) wildlife mods I would love to hear from you. If you don't want to pollute this thread you can sent me a PM. Looking forward to new mods....
Just to add to this, using ASIS to increase spawns of wilderness creatures also works wonders. I have wonderful herds of deer, elk and horses; and in my Whiterun, instead of that
one cow in the town, I have two lovely cows (of different colors! Yay AV!)
On the flip side,
HUGE pack of wolves that chew my butt nearly whereever I go D: SkyTest added in bigger wolf pack spawns, and ASIS just multiplied them even more

I would however suggest adding dragon to the exclusion list, especially if you're like me and already have dragon buffing mods (Deadly Dragons + custom settings) and they don't need the help by having friends >_>;;;
Also @wolverine, about the multiple textures on models. There's no real 'list', surest way is to unpack the original Skyrim .bsas themselves and take a look at the file structure. CK doesn't show the textures file structure (I think) and I'm not sure about other tools like nifskope, whether they can show what textures are associated to a certain model (still learning the tools myself).
@Lev: Where were we suppose to submit bug report files? I got a duplicated EDID error from using Diversified Dragons (clashing with the Werewolf eye files, weird) and got the bug report zipped and ready.
